Abstract

Ce dispositif de transmission comprend : une unité de modulation qui effectue une modulation d'étalement de fréquence sur une série d'informations entrées pour générer un signal de modulation; une unité de temporisation qui donne, à une pluralité de signaux de modulation respectifs obtenus par duplication du signal de modulation généré par l'unité de modulation, des retards ayant des longueurs différentes les unes des autres, une différence entre les retards étant un multiple entier de la réciproque de la largeur de bande du signal de modulation; et une pluralité d'antennes de transmission qui transmettent respectivement la pluralité de signaux de modulation auxquels les retards ont été donnés par l'unité de retard.
